I’m sure the a/c – heating unit was broken a long time before i realized it because it hadn’t been heating since i moved in. However, i didn’t know how strong this little unit should be. I thought maybe the weather was just too much for it. I didn’t realize i needed a repair man until the day we skirted the house when the handyman pointed to my block of powdery ice in the yard and said, “you know that’s broken right?” I turned and looked where he had pointed. He dusted some of the powdered ice off of the unit and said, “it’s not supposed to be like that.” I had thought the ice had come from the sky, as we were standing in the freezing rain, but he assured me it had nothing to do with the weather. So i called a repair man. He gave me a very fair price but i would have to wait for the part to be ordered and shipped from out of town. For a week my daily routine involved de-icing the a/c unit with a butter knife. There were some metal tubes coming out the back of the a/c unit in a loopy motion that reminded me of a hotwheels track. The repair man said this was a problem. It would have to be cut and sautered back together in a straight line. The a/c repair guy was an honest guy that came highly recommended and did good work. The job was done earlier than expected and the unit has worked great ever since. The minute hot air came out of that thing i had an ah-ha moment. I had been cold all winter because the heater was broken.
